Answer:
See below ~
Step-by-step explanation:






The degree is 5, so the largest exponent of the polynomial is 5. This means the answer is either A or B. Choice C is ruled out because the degree here is 7. Choice D is ruled out because the degree here is 6
For choice A, the leading coefficient is 6. This is the number to the left of the variable term of the largest exponent. So we can rule out choice A (because the leading coefficient should be 7)
Choice B is the answer. It has a degree of 5 and a leading coefficient of 7 and also a constant term of 6. The constant term is simply the term without any variables attached to it.
Answer:

Step-by-step explanation:
We know that a triangle has 3 sides, A triangle's interior angles add up to 180 degrees.
Now, let's write this as an equation:

The missing angle is 180° minus the sum of the other two angles.

Subtract the numbers:
